Description
Technical field
The invention belongs to environment-friendly type air purification plant field, be specially a kind of traffic tunnel air dedusting denitration car and dedusting method of denitration thereof.
Background technology
Along with the development in city and the continuous increase of traffic demand amount, unprecedented road construction causes the quantity of highway tunnel and length to be sharp increase situation.As the artificial space of relative closure, tunnel also exists inner air and outer air and exchanges not easily, and the problem such as low visibility and noise and vibration, traffic accident takes place frequently.
In tunnel, airborne pollutant mainly come from the dust produced in automotive emission thing and driving conditions.Car exhaust gas comprises the objectionable impurities such as particulate matter (PM), oxides of nitrogen (NOx).Particulate matter (PM) is the product of non-complete combustion of fuel, main from diesel-powered vehicle, the chromosome aberration of blood lymphocyte can be caused, corpuscle (PM10, PM2.5) can go deep into lung and cause serious harm to respiratory system, particulate matter (PM) or affect the key factor of visbility in tunnel, directly debating knowledge to the vision of chaufeur causes obstacle, and may cause operational vehicle generation safety misadventure.In oxides of nitrogen (NOx) to human body and tunnel air environmental concerns maximum be nitrogen dioxide (NO
2), NO
2be a kind of rufous gas, have strong impulse effect to respiratory tract, after sucking human body, hemoprotein Hb is combined in blood, blood oxygen carrying capacity is declined, can damage the organs such as heart, liver, kidney, very large to body effect, meanwhile, and NO
2still produce acid rain, Los Angelos smog and cause climate change, produce the major cause of smog.
Because tunnel is hemi-closure space, along with the increase of length, hole inner air and outer air exchanges not in time, particulate matter (PM) and nitrogen dioxide (NO
2) existence easily to cause in hole air quality to decline, have a strong impact on the environment in tunnel, serious threat caused to driver and crew in tunnel and the healthy of ventilating shaft discharge side nearby residents.A large amount of highway tunnel construction makes us be faced with very severe tunnel air pollution problem, the particulate matter in tunnel air pollutant and nitrogen dioxide (NO
2) administer very urgent.
At present, Study and appliance both at home and abroad for tunnel air pollution control gets more and more, mainly with ventilation and exhaust purification be technological core, wherein tunnel ventilation adopts the method introducing fresh air from tunnel outer, pollutants is carried out physical dilution, and exhaust purification is by introducing functional accessory purification plant, removing the airborne pollutant in tunnel, alleviating the impact of tunnel exhaust on the outer air environment of Tunnel.
Tunnel ventilation mode is divided into natural ventilation and mechanical ventilation.Natural ventilation brings fresh air into a kind of ventilation type that tunnel dilutes objectionable impurities by the piston action of driving vehicle, and when the magnitude of traffic flow is little, when length of tunnel is shorter, tunnel adopts natural ventilation to meet the demands.Mechanical ventilation is generally divided into transverse ventilation, semi-transverse ventilation and longitudinal ventilation mode, and when the magnitude of traffic flow is comparatively large, when length of tunnel is longer, tunnel generally adopts mechanical ventilation mode.Tunnel ventilation generally adopts winds aloft tower or surface wind tower group, air pollutant concentration in tunnel is reduced by the mode of gas exchanges, but owing to not adding side line purification in long tunnel inside, regional pollution can be caused after the pollutants high-altitude diffusion discharged, jeopardize the healthy of wind tower nearby residents, in addition, be difficult to coordinate at inner city construction winds aloft tower and surrounding landscape, destructible city look and feel.
Exhaust purification is tunnel air Treatment process the most frequently used both at home and abroad at present, mainly concentrates on tunnel dedusting and NO
2in the exploitation of purification techniques and application.But dedusting denitration device needs to be arranged in tunnel with by-pass type, ceiling mounting type, vertical shaft type.In bypass is installed, the air of pollution is forced through a sickle-shaped equipment tunnel of crescent moon, recharge after air-flow purification, reduce resh air requirement demand, and have enough space mounting gas processing assemblies, do not affect main channel wagon flow during maintaining, in the situation such as to catch fire, absorption 30 minutes smog can be continued by high efficiency.When objective condition does not allow to build side line and large-scale air purification apparatus room, will arrange purification plant at tunnel top, the method all has application in the tunnels such as Norway Hell, Nygards and Japanese TokyoBay.In vertical shaft type is installed, air is discharged through the backward upper vertical shaft of purifying station process of level, and can reduce fan energy consumption and the impact on exhaust outlet view, Festnings tunnel and the M30 tunnel, Madrid of Norway are adopted in this way.
The construction of existing tunnel dedusting denitration technology needs to occupy the huge underground space, and not only the cost of tunnel civil engineering input is excessive, and the operation and maintenance cost after dedusting denitration device place in operation is also very huge.Therefore, control and the Treatment process of developing applicable traffic tunnel air pollutants feature have very real meaning.
